With World Maker Faire happening in Queens this weekend, PM couldn't resist stopping by to check out all the cool gadgets and tech. Here's what caught our eye.

Gotham Laboratories' MapperBot

Gotham Laboratories' MapperBot

The team at Go Lab came up with the idea for an asteroid mapper as an entry in the NASA Space Apps Challenge. The MapperBot is made up of a cubesat that houses a camera, 12 mini processors, and a micro ion thruster system. The cubesat will launch from a larger satellite and fly by an asteroid, snapping detailed 3D pictures of the asteroid's surface with a Lytro camera. The thruster system charges and vaporizes the metal of the frame of the cubesat, shooting off ions and allowing for surprising maneuverability without the need to carry a bulkier thruster system (the cubesats are meant to be cheap and disposable). The info gathered from these asteroid flybys will be sent back to NASA, where it'll be turned into a 3D map. From there, scientists will determine whether that particular asteroid is suitable for capture. The Go Labbers at Maker Faire attached their camera to a drone for audience demos.

Chillin' on Mars

Chillin' on Mars

Using data from the Curiosity rover's landing site and an Oculus Rift headset, Linxlab is giving people the experience of standing on the Martian surface. The Chillin' on Mars program lets wearers take a look around the Gale Crater while still enjoying the benefits of oxygen. At Maker Faire, the Oculus was hooked up to a television so the crowds could get a look at what the viewer was seeing. Linxlab plans to add more environments, such as the ocean floor.
